That is the prblem with sedo, their greed loses a lot of sales.
Last week i got an offer on a mid $$ domain, buyer offering $160 which was more than its worth.
However, my email goes, offer $160 less sedo fee $150, you get $10... So im like "ya riiiight". Counter offer of $300 and buyer cancels negs...
Ive never been able to understand sedo fees... The scenario of which i mention above probably happens hundreds of times a day. Why not charge 50% of domain sales under $200. I mean its not as if any sales suck up any admin time...
